DRIFTZERO

DRIFTZERO is an autonomous code migration platform built to make SDK and API upgrades safer and more reliable. Developers provide a GitHub repository, source version, and target version. DRIFTZERO analyzes breaking changes and migration impact, creates a migration plan, applies code changes, generates or updates tests, validates the result, performs security and safety checks, and delivers the migration through an automated GitHub pull request when all verification gates pass. IBM Bob powers the reasoning layer of DRIFTZERO, including change analysis, impact analysis, migration planning, code migration, test generation, and recovery decisions. DRIFTZERO does not treat AI output as proof: generated changes are independently executed and validated through tests, builds, security checks, evidence collection, and deterministic safety gates. The end-to-end demonstration uses a real Express.js 4.22.3 → 5.x migration, while the architecture is designed for progressively verified migration families.
